  /**
   *  @name Standard Stream Objects
   *
   *  The &lt;iostream&gt; header declares the eight <em>standard stream
   *  objects</em>.  For other declarations, see
   *  http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt11ch24.html
   *  and the @link iosfwd I/O forward declarations @endlink
   *
   *  They are required by default to cooperate with the global C library's
   *  @c FILE streams, and to be available during program startup and
   *  termination.  For more information, see the HOWTO linked to above.
